I was surprised the first, and, maybe second, time I fired an AR. Then, when I was shooting NRA High Power Competitions, I found that the RRA NM gun I'd purchased had a buffer that wasn't properly secured with a roll pin. It was there, just not properly secured. After my best ever effort at the lower yardages, two X's and a 10 at 600yds, it locked up the rifle. What the buffer sounded like at that point, was as irrelevant as could be. RRA's lack of response to my calls, e-mails, and letters after the fact, was totally relevant. Lessons learned. I haven't even heard a "sprong" since. (And, that represents many thousands of rounds through various AR platform rifles since). That's just noise. Kinda like the strange sounds emanating from Glock pistols. What does the target say? THAT I'll listen to.
